摘要
本文报告２例脑原发性淋巴瘤的ＣＴ扫描，并结合文献讨论了脑原发性淋巴瘤的ＣＴ表现。平扫肿瘤常呈等密度或稍高密度，边界清楚，瘤周有不同程度水肿，常累及脑的深部结构：基底神经节、丘脑、胼胝体，脑室周围白质及小脑蚓部。增强扫描肿瘤多为均匀强化，亦可为环状强化，偶尔可为脑回状强化。ＣＴ扫描上，脑原发性淋巴瘤易误诊为胶质瘤，脑膜瘤，转移瘤及脑脓肿。本文讨论了脑原发性淋巴瘤与它们之间的鉴别。
T finding of 2
patients with primarycerebral lymphoma were prexented with a literature re-view of the CT
manifestations of primary cerebral lym-phoma.On the plain CT scan.nost of lymphomaswere
either hyper-or isodense. well demarcated,andhad vari variable surrounding edema.The tuniors
weremostly xitutited in the deep structures of brain:thehxal ganglia, corpus
callosum,Periventricular whitematter and vermis of cerebellum. On the postcontrastCT scan,
cerebral lymphomas showed a homogeneouscontrast enhancement.Ring
enhancement.occasional-ly gyral enhancement also may be seen. On the CTscan. priniary
cerebral lymphorna were usually misdi-agiiosed as glioma,meningioma,metastases and
ab-scess. The difference between lymphoma and the the above lesions was was discussed.
